中文摘要： 船舶能效提升理论是适应船舶节能减排趋势的理论基础。通航环境在很大程度上影响船舶主机能效，而且诸因素对船舶的影响机理尚未能得到系统和深入研究，是航运界关注的热点之一。本研究选择长江营运船舶为研究对象，针对通航环境要素对主机能效的影响特点，采用数学分析与实验验证相结合的方法，规避机理分析的复杂性和不确定性问题，分析随机环境因素对主机能效影响的统计特征，研究环境诸因素对船舶主机能效变化的影响机理，区分重要因素和次要因素，建立主机能效与通航环境的动态响应关系模型，提出在风向-流速-水深等通航环境要素作用下的船舶主机能效提升理论与方法，服务于航路规划，提高船舶管理精细与科学水平，为航运企业开展节能减排提供新策略，推动绿色低碳航运的发展。

英文摘要： Ship energy efficiency promotion theory provides a concrete foundation for ship energy conservation and pollution reduction. The voyage environment influences the ship propulsion energy efficiency significantly, but the machanisms have not been thoroughly analyzed, which is one of the hot topics in shipping industry. Based on the characteristics of voyage enviromental impacting on the ship propulsion engine, this study would choose merchant ships in Changjiang river as research target, and combines mathematical analysis and experimental verification to evade the complexity and indeterminacy of mechanism analysis, the impacts to vessel propulsion energy efficiency from each envirionment fators will be studied, important fators and secondary fators would be distinguished, the dynamic response relationship theory between propulsion engine energy efficiency and vovage envirioment would be developed, and the energy efficiency promotion theory and method for propulsion engine would be summarized, under the impacts of vovage envirionment, which would serve the vovage planning, improve the precise and rational level of ship management, supply new strategy for shipping company to save energy and protect environment, thus promotes the green and low-carbon developments in shipping.
